Having trouble enabling overclocking on my GTX 970
Tried drivers 375.66, 378.13 and 381.22
Coolbits is set in my Xorg.conf, tried 28 and 31
Powermizer tab on nvidia-settings shows “Editable Performance Levels”, but entering values into them does nothing. Screenshot here http://i.imgur.com/wrodzGQ.png
nvidia-settings does not report attributes I would expect for adjusting memory clock
$ nvidia-settings -q all | grep ‘Memory|Offset’
Attribute ‘GPUMemoryInterface’ (capablanca:0.0): 256.
‘GPUMemoryInterface’ is an integer attribute.
‘GPUMemoryInterface’ is a read-only attribute.

Attribute ‘GPUOverVoltageOffset’ (capablanca:0.0): 100.
The valid values for ‘GPUOverVoltageOffset’ are in the range 0 - 87500 (inclusive).

“nvidia-settings -q all” does not list GPUGraphicsClockOffset or GPUMemoryTransferRateOffset
“nvidia-settings -e” shows the following
$ nvidia-settings -e GPUGraphicsClockOffset
Attribute 'GPUGraphicsClockOffset':
- Attribute value is an integer.
- Attribute is not written to the rc file.
- Attribute not queried in 'query all'.
This is the offset amount, in MHz, to over- or under-clock the Graphics Clock. Specify the performance level in square brackets after the attribute name. E.g.,
'GPUGraphicsClockOffset[2]'.
$ nvidia-settings -e GPUMemoryTransferRateOffset
Attribute 'GPUMemoryTransferRateOffset':
- Attribute value is an integer.
- Attribute is not written to the rc file.
- Attribute not queried in 'query all'.
This is the offset amount, in MHz, to over- or under-clock the Memory Transfer Rate. Specify the performance level in square brackets after the attribute name. E.g.,
'GPUMemoryTransferRateOffset[2]'.
Trying to set either of the above attributes throws an error
$ sudo nvidia-settings -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=100'
ERROR: Error assigning value 100 to attribute 'GPUMemoryTransferRateOffset' (capablanca:0[gpu:0]) as specified in assignment '[gpu:0]/GPUMemoryTransferRateOffset[3]=100' (Unknown
Error).
Is overclocking supported on this card? Please confirm with your card Vendor. May be they will suggest any vbios change. Also did you test with any older nvidia driver?
Having same problem with 460GTX and 570GTX, both card were overclockable like a year ago, but now it isn’t working. I’ve tried command line overclocking/underclocking and nvidia control panel overclocking. Either way it isn’t working.
>>card were overclockable like a year ago
What do you mean by that? Can you explain more? Please attach nvidia bug report. Is any older driver don’t have this issue for your cards? Who is Vendor of your card?
460GTX is from MSI, 570gtx is from point of view. I was trying this feature like a year ago, I don’t remember which driver I’ve had. I’ve tried this like a week ago and it’s not working. I open nvidia-settings, go to overclocking, set gpu overclock to 10, hit enter and nothing happen. Year ago it was working. nvidia.log.gz (99.7 KB)
Did you solve the “Unknown Error” problem with the EVGA GTX 970 SSC trying to overclock on linux?
I have the same problem: tried Coolbits 8 and 12 and with and without “RegistryDwords” “PerfLevelSrc=0x2222”
Ubuntu 14.04 Driver version 375.66
Perhaps a VBIOS update is needed?
